Within the lightning tribulation, a chaotic electromagnetic world was taking shape.
Countless chaotic runes flickered and drifted within it: Maxwell's equations, the formulas for Coulomb's law, Gauss's law, Ampère's circuital law, Faraday's law of induction... all the crystallized wisdom of past sages who had explored electromagnetism, one of the four fundamental forces of physics.
The chaotic electromagnetic world expanded from one kilometer to two, then three... until it reached the threshold of nine kilometers, where it slowly stopped.
"It isn't ninety percent anymore."
"It's a hundred percent."
Divine Mechanism Heavenly Lord breathed a sigh of relief and explained to the Heavenly Lords around him, "No terrible misfortune struck, and no great accident occurred. His luck was just as it had always been: perfectly ordinary, neither good nor bad."
"Look at that Void Refining space."
He pointed to the world taking shape, where electromagnetism was giving rise to all kinds of plants. "It's nine kilometers across. That's reached the average level of the Immortal Orders' great powers, which is quite good."
"According to various scriptures, 9.9999... kilometers is the limit of a Void Refining cultivator's soul-based Void Refining space."
"The nines after that decimal point go on forever."
"The Great Sun Sword Pavilion's Integration scriptures record that the farther it expands, the more nines appear after the decimal point and the greater its potential. This represents a certain limit—the limit to which one has developed one's soul and body. The closer one comes to that limit, the greater one's hope of advancing to Integration. It has to do with some rule of the world."
"It seems that the closer a Void Refining space is to its limit, the more it resembles the real world and the Heavenly Dao, reducing the difficulty of Integration."
"That is why the Great Sun Sword Pavilion
